Wi-Fi 7 MLO: Hype vs. Reality

Wi-Fi 7 introduces Multi-Link Operation (MLO), a feature designed to boost internet speeds and connection stability by utilizing multiple frequency bands simultaneously. This technology aims to overcome limitations of older band-steering methods that could cause interruptions or slow performance. MLO offers two primary implementations: Simultaneous Transit and Receive (STR) mode, which uses multiple router radios, and Enhanced Multi-Link Single Radio (EMLS) mode, using a single radio to switch bands more efficiently.

Despite significant promises, the full potential of MLO remains largely unfulfilled. A February 2026 report indicated that no Wi-Fi 7 routers tested supported the advanced multi-radio STR version of MLO. Additionally, network-wide adoption is hindered by compatibility issues. For MLO to function optimally, all devices on the network, including phones and laptops, must be Wi-Fi 7 compatible. Using MLO with mixed Wi-Fi standards or non-compatible devices can lead to instability and negate the intended performance gains.

Given these challenges, a blanket recommendation for enabling MLO is difficult. For users integrating a Wi-Fi 7 router into an existing network or lacking compatible devices, disabling MLO is advised for stability. However, users with a complete Wi-Fi 7 setup and compatible end-user devices can experiment with enabling MLO to assess performance differences. Router manufacturers like UniFi, eero, Linksys, and ASUS offer MLO controls in their respective interfaces, though it is often disabled by default due to potential compatibility concerns.
